Industrial NetworkingThis section describes the data and command exchange communications options available for CJ1 systems:

Collect and Share Valuable DataNetworking has become one of thecore requirements of automationsystems today becausetomorrow’s competitive edgecomes from factory floor andenterprise-wide data. More andmore, factory operations arebecoming dependent on machineand line productivity data.

Automation systems that were once isolated and stand-alone nowprovide valuable data for process optimization and statisticalanalysis.

Omron’s Industrial Networking options provide easy-to-implementconnections from controllers to Data Acquisition Systems andSupervisory Control Systems that is unmatched in the industrytoday. This is very easy to accomplish using Omron’sProgrammable Controllers because:

1) the Communications Modules provide the intelligence for routing the commands or data, and

2) the memory of the processor is organized so that communications requests can access data areas in the processor without interrupting the control function of the CPU to do “block transfers.”

Data memory provides a “scratch pad” for information to be writtento and read from. It can also be the “working” memory to which realworld I/O changes are automatically written. This allows the user todesignate the desired data, what it means and what should be donewith it from a remote location, without interfering with the executionof the control program.

The final key to this capability is Omron’s unique middlewareproduct called FINS (Factory Intelligent Network Service) that allowsmessages and information to be seamlessly routed across and upto three networks. This means that a message or command thatoriginates from a computer and originates on Ethernet, can routethrough a factory floor Programmable Controller over ControllerLink and, finally, access I/O data in a “micro” controller over either aserial link or DeviceNet.

Omron Simplifies Setup for Network Communications

Comparison of Omron’s Data Link to Traditional Block Transfer

Examine the realities and costs involved in building the network communications that let you integrate plant floor data with front officesystems. Two considerations move to the top of the list: flexibility to handle changing requirements easily and the ability to integrate legacyproducts. The table below clarifies the advantages of Omron’s approach.

Handling legacysystems

Makes available aneasily expanded areaof data that isaccessible to all PLCson the network. Datarequests are handledoutside the scan timeby co-processors inthe communicationsmodules.

• Use dialog box “wizard” setup• User defines how much data is to be sent via the

Data Link, what memory location is to be used and how much to “read” from all other network nodes

The screen capture shows a typical Data Link set-up inprogress. The user can define:• How much data gets sent• What memory area is the source of the data and• Where to put received data

• Amount of data to be handled, changing where it goes or adding a new node is as simple as the initial setup

• No impact on program execution

Data Link reduces the original cost of programming insetting up the routing tables for exchange and offersmaximum flexibility for future changes, requiring minimalediting to routing table data.

Omron’s CX-Programmer software covers all Omron’sprogrammable controllers with networking capability,from micros up to large rack systems. Access to thememory areas available for each model is selected in adialog box when the specific model is designated.

Defines a point-to-pointconnection between a desiredindividual data point in a PLC tomake a specific link to therequesting PLC and define theamount of data that can beexchanged. Typically limited to 64 words.

• Use special Move instructions• Must follow any Read or Write command• Error checking is done by programming and data

consistency must be checked due to scan cycle mismatches

Printout shows the first rung of an extensive programrequired to define point-to-point data exchange and toverify data consistency.• Error checking is done by programming • Size of transfer affects program cycle timing

• Program must be adjusted if data size changes; program execution time changes

• If different models are communicating, up to 3programming software packages could be required

Long hours of programming each individual point-to-point exchange followed by system testing to be surecycle time is acceptable, followed by any modifications tobring cycle time back into bounds. Future changes aretime consuming editing projects.

Depending on the manufacturer, multiple programmingsoftware packages are required to set up and modify theblock transfer ladder programming across the full rangeof PLCs in an installation. Finding and hiringprogrammers with experience in older platforms becomesdifficult as time goes by.

J Network Capabilities

Basic Capabilities

• Compatible with 100Base-TX (100 Mbps) and 10

Base-T (10 Mbps)

• 254 total nodes possible

• SNTP client functionality for automatic clock adjustment

• DNS client functionality to specify servers by host name

• Compatible with earlier CS1/CJ1 Ethernet modules

E-Mail Capability

• Transmit e-mail attachments from the Ethernet module

using an SMTP server to acquire user-created data,

error log data, and module status data.

• Using a POP3 server, the user can send commands to

the Ethernet unit via e-mail.

Internet Capability

• Host computers that acquire a dynamic IP address (us-

ing DHCP) can send commands to the PLC and receive

responses.

• Multiple FINS supported applications within the comput-

er can go on-line simultaneously.

• Using FINS communications, both TCP/IP and UDP/IP

are supported.

• Using the built-in FTP server, files can be read from or

written to the mounted memory card.

• Using FINS communications, connectivity with devices

on other networks is possible (renting services).

• Socket services (TCP or UDP protocols) allow for

Ethernet connected devices to send and receive data.

• FINS commands can be sent or received by PLCs or

computers on the same Ethernet network.

J Ethernet Network

Take advantage of a wide range of communications capa-bilities. Communicate with PLCs remotely through the Inter-

net or locally through an Ethernet network. Transfer datawith TCP/IP or UDP/IP socket services, execute Omron’sstandard FINS commands, transfer and receive memorycard files with FTP, send e-mail with SMTP or receive e-mail with POP3. Select the communications services that

are required and flexibly connect PLCs on an Information-Level Ethernet network.

Omron’s Ethernet modules support the full TCP/IP modelfor maximum flexibility in data exchange. Omron useseasy-to-establish routing tables to share common datatable contents instead of programming requests to sharespecific blocks of data with specific PLCs. With Omron, all

communication modules can share data within PLCmemory. This allows great flexibility for future control modi-fications without substantial reprogramming effort.

Controller Link: Peer-to-Peer Control Network

Why Use Controller Link?

Omron’s Controller Link complements Ethernet byproviding access to mission critical information while notdisturbing the timing or execution of the main controlsystem. It was designed specifically to handle large datatransfers in applications with these requirements.

J You’ll Achieve These Goals

• Large amounts of information can be transferred from

controller to controller automatically, and/or by using

specific commands.

• You will utilize a supervisory system that will be

constantly updated as it coordinates the output from

one manufacturing cell to the next.

• Timing will be deterministic so that performance is

repeatable.

These requirements can be met perfectly using Omron’sController Link network, a network designed specificallyfor critical timing and large data transfers. Controller Link

provides these capabilities by combining an automatic datalink service with a messaging service that enables sendingand receiving data when required by process conditions.The result is highly flexible data sharing that provides de-terministic system response with highly effective use of

data areas within the PLCs. (Refer to the Data Linksillustration on this page.)

J Features

• Controller Link supports up to 62 nodes (using Repeat-

er Units), and each node can transmit up to 1000 words

(16 bits = 1 word) of data.

• Determinism is accomplished through the use of a

token passing scheme, and CRC error checking

ensures that the data gets through.

• Controller Link’s two media options are Shielded

Twisted Pair (STP) and optical fiber.

• Like all Omron networking products, Controller Link

supports transparent network routing and gateway

functions while providing deterministic high-speed

data transmission.

J Controller Link Provides Two PowerfulServices

all the other connected controllers.

Data Links

Data links automatically exchange data in preset areasbetween nodes on a network. Efficient, large-capacity datalinks can be flexibly created between PLCs and host com-puters on the same network.

Automatic Data Link

Each node has a defined part of the shared memory that allother nodes can read, but not write. In this way, all informa-tion that needs to be shared is constantly updated andavailable to all nodes on the network.

Node 1Node 2Node 3

Manual Data Link

Each “node” has an area of shared memory that it writes to.If a node does not require the information from anothernode, it simply does not “read” that memory area.

1:N Data Link Allocation

V1 Controller Link modules support 1:N Data Link alloca-

tion. 1:N Data Link allocations allow for the master node(Node 1) to acquire data from all slave nodes (remainingnetwork nodes) on the network in a stack format from low-est node number to the highest. This allows for only the

desired data windows within a node to be transferred ontothe master node data stack.



The DeviceNet Solution

Multivendor, Multibit Network

J High-Speed Network for FADeviceNet is a high-speed network optimized for applica-tions that require control of I/O on factory floor machinery.

Omron has developed an extensive offering of DeviceNetcompatible products that reflect Omron’s commitment to

meeting two overriding operating performance principles:(1) intuitive operation and (2) ease of deployment.

To accomplish these objectives, powerful features havebeen built into Omron’s DeviceNet Master Modules —

features not seen in DeviceNet Masters from othervendors.

Omron’s DeviceNet Master Modules provide the bestpossible DeviceNet CAN performance while simplifyingnetwork setup and configuration.

As a founding member of ODVA (Open DeviceNet Vendor’sAssociation), Omron has implemented DeviceNet in amanner that assures ease of use and deployment. In thelist that follows, you will see that our DeviceNet masterunits offer powerful features not found in the DeviceNet

masters from other vendors.

Highlights of Omron’s DeviceNet Master Modules

• Automatic network enrollment and I/O allocation.

Configuration tools are not required to set up, map and

allocate the network into controller memory.

• I/O allocation to any CPU memory area without the

use of a configuration tool. Allocate I/O using CX-


• Omron DeviceNet Master has FINS capability. This

allows DeviceNet to be used to route data or to carry

programming commands to FINS-capable devices, al-

lowing communications capabilities through Omron net-

worked devices. FINS is a communications protocol

developed by Omron and embedded in the firmware of

products such as network communication master

modules.

• Large buffer memory ensuring data integrity for

explicit messaging. Omron’s master has 200 words of

buffer memory to ensure consistent data integrity.

• Message handling capacity eliminates a need for

any space between messages. Omron’s master

provides the fastest system throughput possible by

eliminating any requirement for quiet space between

messages.

All of the above features provide the best possibleDeviceNet performance while simplifying network setupand configuration. Omron’s DeviceNet slaves are fully

compatible with the latest standards to ensure opencommunication with legacy masters from other vendors.Wireless DeviceNet, an Omron exclusive combination oftransmitter and receiver, opens many new networking

possibilities. It removes the barriers of wires and fixed to-pologies, opening the door to distributed intelligence andmore flexibility in the location of networked I/O.

ProfiBus-DP Master Module

CJ1W-PRM21

DeviceNet Module

J Features

• CPU bus module where up to 16 masters can be

mounted per PLC.

• Supports cyclic communications with up to 125 slave

stations per network.

• Total size of I/O data for all ProfiBus masters mounted

per PLC must not exceed 7,168 words.

• Utilizes FDT/DTM Technology:

-- FDT (Field Device Tool): An FDT container ap-

plication (ie. CX-ProfiBus) allows for configura-

tion, manipulation and monitoring of network

nodes.

-- DTM (Device Type Managers): A Microsoft

COM-component provided by the device manag-

er that allows for interactive configuration and

diagnostics, similar to a printer driver.

• ProfiBus allows for multiple masters per network and

utilizes a token passing procedure which allows the

token possessing master to poll its assigned slaves.

• ProfiBus Configurator enables easy monitoring of the

status and settings for network devices, and provides

error information for the master.

ProfiBus-DP (PROcess FIeld BUS -- Decentralized Periph-

ery) is a vendor-independent, open fieldbus standard for awide range of applications in manufacturing, process andbuilding automation. Vendor independence and transparen-

cy of operation are guaranteed by the ProfiBus standardEN50170. With ProfiBus, devices of different manufacturerscan communicate without special interface adjustments.

J Diagnostic Messages

• Device Related Diagnostics: Messages to determine

the operational status of the whole device (ie. over tem-

perature, low voltage)

• Module Related Diagnostics: Messages to identify an

error in a specific range of I/O for a slave station (ie. an

8-bit output module)

• Channel Related Diagnostics: Messages indicating an

error at a given input or output (ie. short circuit on out-

put 5)

Note: ProfiBus master modules support the storage of up to 80error events.

J Troubleshooting

• Extensive self-diagnostic function at startup

• Dedicated status flags, indicating if I/O data is being

exchanged within the assigned slave stations

• Dedicated status flags, indicating if new slave diagnos-

tic data is available

• Extensive status and error flags, indicating the status of

the module and the ProfiBus network

• Error log for recording error history data

All the Capacity and Advanced Capabilities Needed for HMI, Communications or Data Processing

Command

Response

J Other Protocols

OMRON provides all of the capabilities and capacityyou need for the advanced programming required forHuman-Machine Interfaces (HMI), communications,

data processing, and other required applications.

Host Links

Host Link (C-mode) commands or FINS commandsplaced within host link headers and terminators can be

sent to a host computer to read/write I/O memory, read/control the operating mode, and perform other opera-tions for the PLC.

Unsolicited messages can also be sent from the PLC to

the host computer by sending FINS commands fromthe ladder program using the SEND(090), RECV(098),and CMND(490) instructions.

1:N NT Links

The PLC can be connected to an Omron OperatorInterface Terminal via RS-232C or RS422A/485 ports; I/Omemory in the PLC can be allocated to various OperatorInterface Terminal functions, including status controlareas, status notifications areas, touch switches, lamps,

memory tables, and other objects.

Addition of High-Speed NT Links

High-speed NT Links (three times faster than conventionalhost link transmissions) are possible with the NS Series

and version 2 of the NT631 and NT31 Series. This speedis particularly important when connecting to more than oneOperator Interface Terminal.

Note: Up to eight Operator Interface Terminals

can be connected to a PLC using 1:N NT

Links.

create protocols for any non-Omron device.

Omron’s CJ1 offers serial communications in addition

to what is standard on the CPU with additionalCommunication Bus Modules. These modules arenecessary to expand on the CPU’s Serial Port func-tionality. By incorporating a separate communicationbus, all data exchanges and setting changes do not

affect the cycle time of the control functions.

An exclusive time-saving setup feature built intoOmron controllers, called Protocol Macro, containsthe hand-shaking commands for many of Omron’scontrollers with serial communications. A ProtocolMacro instruction in the PLC, called from the ladderdiagram, designates the serial device and serial

communications starts up automatically. To quicklydevelop a protocol macro for serial devices, useOmron’s CX-Protocol software. It contains typicalcommands to quickly create the short hand-shakingprogram and register it for later use in the PLC’s

memory.

The Two Main Functions of Protocol Macros

1. Creating Communications Frames

The communications frames can be easily createdaccording to the specifications required by the con-nected device. Data from I/O memory in the CPU canbe easily included as part of a communications frameto read from or write to I/O memory. CPU

2. Creating Frame Send/Receive Procedures

The required processing, including sending and receivingcommunications frames, can be performed one step at atime based on the results of the previous step, and thenCX-Protocol Software can be used to trace send andreceive data.

RS-232C to RS-422A Adapter Unit

Long-Distance Transmissions and No Separate Power Supply

NT-AL001

The NT-AL001 is used to connect an Operator Interface

Terminal or other device with an RS-232C terminal to a

device with an RS-422A terminal.

J Features

• Long-distance transmissions are possible through an

RS-422A interface. By converting from RS-232C to

RS-422A and then back to RS-232C, a transmission

distance of up to 500 m can be achieved.

• No power supply is required. If the 5-V terminal

(150 mA max.) is connected from the RS-232C device,

a separate power supply is not required to drive the

Adapter Unit.

• Duct wiring can be used. The removable terminal block

enables wiring not possible with D-sub connectors.

(The RS-232C interface is 9-pin D-sub.)

Simple Communications Unit

Provides Easy Interface between Omron PLCsand Temperature Controllers or Digital Panel Meters

CJ1W-CIF21

Data transmission between Omron Process andTemperature Controllers and Panel Meters is automaticallyhandled via the DM area of the CPU. There is no need forcommunication commands to handle these CompoWay/F

or SYSWAY communications.

Data read from the components is automatically stored in

the designated area of the DM. Conversely, data from thedesignated area of the DM is automatically written to thecomponents. This simplifies PLC changes in the settemperature (SP) and in monitoring the present value (PV)of Temperature Controllers and other components.

J Features

• Interface with Omron Process and Temperature

Controllers that implement either CompoWay/F or

SYSWAY protocols (will support a combination of both

types of components).

• Up to 18 units can be connected to one PLC

• Compatible with CS1, CJ1, CQM1H, and CPM2A

PLCs.

• CIF21 unit is identical in size to CJ1 Series PLC

Modules.
